Comming off a roundabout behind a slow lorry onto a d/c, me laden down with a passenger and all my tools, jack and trackday wheels.
Started about 20, and i was pulling on him, from about 40-70 it was neck and neck, and over 70 he was pulling on me, got to being about a car length behind at 120, when i had to slow down for a car in the inside lane.
Next island, he was about 10 car lengths ahead, i closed the gap almost right up again, not sure how hard he was trying at this point tho
